Greatest point of all time?

There's no specific criteria for this, just tell us your favorite point, and why. Links are also nice if you have a good video of it. You may pick a point because Of its significance in a match, for the shotmaking skill, for the crazy athleticism involved, whatever. Those are just some ideas.

Personally, I'm a fan of shotmaking, so improv shots and similar things usually get my vote. But the point in last years USO final, where Novak attacked relentlessly yet Rafa kept defending until djokovic finally managed a backhand winner... That was pretty epic. It reminded me of the quote from The Dark Knight "This is what happens when an unstoppable force means an immovable object."
